Every now and then, one has to visit your enemy and competitor, as Richard Nixon realized in the early 1970'ties, when he visited The People's Republic of China, and shaked hand with communist leader Chairman Mao Zedong (see above). I imagine Nixon felt a bit unsecure when he, as an american, visited a traditional enemy on his home ground, almost like sticking your head in to the lion's den.

Uppsala and Lund Universities, being the oldest and most prestigious universities in Sweden, are often seen as competitors, but luckily we have not been close to armed conflict, like the US and China, and we are hopefully a bit closer to each other than Nixon and Mao. I was therefore honoured when I was offered to sit the thesis committé of Niclas Vallin, one of my colleage Anna Qvarnströms PhD-students, together with Prof. Andrew Hendry from McGill University (Canada). You probably remember that Andrew was also the opponent of my student Fabrice Eroukhmanoff in Lund, a couple of years ago, and then Anna Qvarnström was in the thesis-committe.

On Thursday last week, Andrew and I also gave tandem talks at the Evolutionary Biology Centre (EBC) about the importance of ecological speciation, and its alternatives. We both took a critical look at ecological speciation, albeit from different angles, and Andrew writes more about it here.Briefly, Andrew questioned how often ecologically divergent selection leads to the completion of speciation, something which he calls "ecological non-speciation" , whereas I attacked ecological speciation with some examples of radiations which are unlikely to have speciated through ecological means and niche-based divergent selection, which we can call"non-ecological speciation".

Lastly, I have to say I really enjoyed going to Uppsala (in spite of our historical antagonisms!), and to participate both in the thesis-committe of Niklas Vallin, and listen also to the thesis-defence of another PhD-student, Paolo Innocenti, who has worked on the transcriptomic consequences of sexual conflict in Drosophila. Interestingly, Paolo has worked both with Jessica Abbott and Tom Gosden, my two first PhD-students, so this is really a small world. And although Lund might still be the best university in Sweden, there is clearly room also for Uppsala, especially when they open up and collaborate with people from Lund.

About us

We are a group of evolutionary biologists consisting of three PI:s (Jessica Abbott, Erik Svensson and Tobias Uller), and several postdocs, PhD-students and Master's students. We focus on ecology and phenotypic evolution, and topics as sexual selection and sexual conflict, epigenetic effects, frequency-dependent selection, and speciation processes in natural populations.

Research approaches include experimental evolution, quantitative genetics, experimental field studies of natural and sexual selection, and phylogenetic comparative methods. Our main study organisms are mainly invertebrates (insects, isopods, flatworms), although we also study lizards and birds.
